Slight burn/tingle tip of penis/urethra itches after ejaculation/not urination/took 2g azithromycin/now have testicle soreness and cough/no sores/bump?

See Dr. You may have / have had urethritis, and now be developing epididymitis or orchitis. Cannot say for sure w/info above. Need to be evaluated by a dr--yours, urgent care, urology, or county health dept's "std clinic" if available. Do not delay--pain gets worse & can impact future fertility.
